How this service works
The OpenRouter for AI-agent tools: one gateway, one wallet, every capability. Built-in tools, forged tools, a global verified business directory and 2,000+ aggregated x402 services, all paid per call in USDC via x402 (HTTP 402). No signup, no API key.
Output
Returns a JSON object with an `ok` boolean field indicating whether the supplied ABN passes format and check-digit validation. No external lookup is performed; this is an offline algorithmic check.
Example use cases
Supplier ABN check before payment
“Before I pay this invoice, can you confirm that the ABN 51 824 753 556 is a valid Australian business number?”
Onboarding form ABN verification
“A new vendor filled in their ABN as 32123456789 on our onboarding form — can you check if that's a legitimate ABN format?”
Bulk data cleanup ABN screening
“I've got an ABN from our records — 99 999 999 999 — can you validate whether it passes the ABN check digit rules?”
Technical details
Endpoint
POSThttps://toll402.dev/v1/t/abn_au_validate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, cheap, offline ABN format and check-digit validation without requiring a live ABN lookup against the Australian Business Register. Ideal for pre-submission validation, onboarding flows, or data cleansing where real-time registry confirmation is not required. At $0.001 per call via x402 USDC, it suits high-volume validation pipelines without API key management overhead.
Side effects
- Malformed input (non-numeric characters beyond spaces) may return ok: false or an error
- ABNs with incorrect length return a validation failure
- Network or gateway errors return HTTP 4xx/5xx from Toll402
- Payment failure via x402 results in HTTP 402 with no validation performed
